Those Muay Boran guys used to be able drop a horse with their heads on the battlefield.

All that stuff was taken out when it became the sport of Muay Thai and was watered down for the ring with loads of rules imposed, of course.

Would've been freaking sweet to have been there back in the day and seen those ancient Thai warriors conditioning their skulls using palm trees, coconuts, walls and bags filled with lead balls for 12hrs+ per day....

The best justification for right-handed Fascism in this regard was "battlefield"

A dense block of 500 warriors charging into battle drawing their swords right handed, a couple in the middle draw left handed... limbs flying everywhere.

Has some merit I guess.

No, it doesn't. To add to what DCS said, Aikido was never a battlefield art.

Calm down, it's only ones and zeros.

Seems to me that the concept is to wear the sword opposite the main arm, so there's enough room to draw the blade clear of the scabbard. If there was a social stigma on a sword on the right, what was a left handed samurai to do?

When I started learning the sword forms in my old school, I learned right handed.

Oh, forgot to mention that I'm left handed for those who don't know me
